And a sliding member 7 slidable in the front-rear direction.
[0031]
The first half of the case 2 is formed in a substantially rectangular shape, and the second half is formed in a substantially inclined shape. The front and rear coincide with the front and rear direction of the vehicle. The case 2 includes a vertical substrate portion 8, a lower horizontal wall portion 9 as a peripheral wall around the substrate portion 8, a front wall portion 10 raised in a curved shape, and an upper horizontal short wall portion 11. And a curved wall portion 12 in the latter half following the upper wall portion 11.
[0032]
A narrow mouth portion 13 for harness derivation is provided in the upper wall portion 11, and one end of the wire harness 6 is fixed by a fixing portion 14 in the vicinity of the mouth portion 13. The wire harness led out from the mouth portion 13 is connected to a wire harness and an auxiliary machine (not shown) on the slide door side by a connector 15. The case 2 is fixed to the inner panel of the sliding door (not shown) by fixing means (not shown) such as bolts and locking clips.
[0033]
The cover 3 is provided in parallel with the plate shape so as to face the substrate portion 8 and is fixed to the peripheral walls 10 to 12 by a locking means (not shown) such as a locking frame piece and an engaging protrusion. The lower end of the cover 3 is positioned slightly above the lower wall 9 of the case 2, and a horizontally long slit-shaped mouth portion 16 is formed between the cover 3 and the lower wall 9. The other is led out and connected via a connector 18 to a wire harness (not shown) on the vehicle body side via a harness fixing portion (fixing tool) 17 on the vehicle body (fixed structure) side.
[0034]
The harness fixing portion 17 may have a structure that supports the wire harness 6 so as to be rotatable in the circumferential direction. In addition, instead of the harness fixing portion 17, a rectangular cylindrical long or arcuate auxiliary protector that extends between the sliding door and the vehicle body is provided, and the vehicle width immediately after the sliding door is opened (just before full closing) is provided. It is also possible to slide and store the vehicle body side as the direction moves.
[0035]
The case 2 and the cover 3 constitute a protector 4. A horizontally long space for harness storage is formed in the protector 4. The lower opening 16 of the protector 4 extends straight from the front wall 10 of the case 2 to the opening 19 at the rear end. The rear end opening 19 may be blocked by a vertical wall (not shown).
[0036]
The sliding contact guide 5 is raised substantially in a mountain shape from the lower wall 9 (the lower end of the substrate portion 8) and the lower end of the cover 3, and is formed symmetrically with the substrate portion 8 and the vertical substrate portion of the cover 3. . The sliding contact guide 5 on the cover 3 side is shorter than the substrate portion 8 side by the dimension of the mouth portion 16. The mountain shape of the sliding contact guide 5 may be curved or linearly inclined, and has inclined portions 5 a and 5 b having substantially the same length in the first half and the second half of the protector 4.
[0037]
As shown in a cross-sectional view of one form of the sliding contact guide 5 in FIG. 4, the sliding contact guide 5 is formed in a rail shape on the inner surface of the substrate portion 8 of the case 2 and the inner surface of the cover 3. The rail 5 has a curved surface 5d for receiving the spherical sliding member 7 on the upper side and is formed in a substantially triangular cross section. The protruding length of the rail 5 is set to a length that allows the wire harness 6 to be inserted between the pair of rails 5 with a space. A space for harness insertion exists between the pair of rails 5.
[0038]
The spherical sliding member 7 is formed of a synthetic resin material, for example, divided into left and right parts, and a locking means such as a locking claw and an engagement recess in a state where the wire harness 6 is sandwiched in the inner hollow hole 20. (Not shown). When the synthetic resin corrugated tube 21 (FIG. 1) is attached to the outer periphery of the wire harness 6, the inner surface of the sliding member 7 is engaged with the groove in the circumferential direction of the corrugated tube 21. The sliding member 7 is rotatable in the circumferential direction and is prevented from moving (fixed) in the longitudinal direction of the harness. In FIG. 1, the outer diameter of the sliding member 7 is set to be larger than the width of the lower mouth portion 16, so that the sliding member 7 does not protrude outward from the mouth portion 16.
[0039]
It is also possible to form two pairs of rails 5 and to hold the wire harness 6 between the upper and lower rails 5 without dropping off. Further, the cross-sectional shape of the rail 5 can be appropriately set according to the shape of the sliding member 7. Further, the sliding member 7 is not divided, and the wire harness 6 is taped around a protruding piece (not shown) in the longitudinal direction of the harness in a state where the wire harness 6 is inserted through the central hole 20 (FIG. 4). It is also possible to fix with. It is also possible to form the spherical sliding member 7 integrally with a protective tube such as a corrugated tube around the wire harness.
[0040]
According to the rail 5 and the sliding member 7 of FIG. 4, the structure is simplified and the cost is reduced by bringing the sliding member 7 into contact (sliding contact) with the rail 5 using the weight of the wire harness 6. The In FIG. 1, the sliding member 7 and the sliding contact guide 5 of the form of FIG. 4 are shown.
[0041]
FIG. 5 shows another form of the sliding contact guide, and this sliding contact guide 5 ′ is a mountain-shaped guide hole (cam hole) formed through the substrate portion 8 and the cover 3 of the case 2. . The shaft portion 22 of the sliding member 7 'is slidably engaged with the guide hole 5'. The front and rear ends (lower end) of the guide hole 5 ′ do not open at the lower end of the cover 3, so that the shaft portion 22 does not come off from the cover 3.
[0042]
The sliding member 7 ′ is formed of a synthetic resin material, and is annularly fixed to the wire harness 6 so as to be clamped or engaged with a concave groove of the corrugated tube 21 (FIG. 1), and an annular portion 23 And a pair of shaft portions 22 projecting from the portion 23 in the radial direction. The annular portion 23 is divided into, for example, left and right, and is fixed to each other by locking means. Or it is fixed to the wire harness 6 by tape winding or the like with a protruding piece (not shown). Or it forms integrally with the protection tube of a wire harness outer periphery.
[0043]
According to the form of FIG. 5, since the sliding position of the sliding member 7 ′ is accurately defined by the guide hole 5 ′, the wire harness 6 contracts in the protector 4 with an accurate diameter, and the sliding member 7 'up and down play is also prevented.
[0044]
When the sliding door of FIG. 1 is fully closed, the sliding member 7 is located at the rear end of the sliding contact guide 5 (the lower end side of the latter inclined portion 5a). The wire harness 6 inclines upward from the sliding member 7 along the inclined portion 5a of the sliding contact guide 5 and draws a small ring downward in the latter half of the protector 4 so as to intersect the wire harness rear portion 21 and upper mouth portion 13. Along the rear wall 12, it rises in a curved shape as indicated by reference numeral 6a. The wire harness rear portion 21 is pulled rearward from the lower mouth portion 16 toward the harness fixing portion 17 on the vehicle body side.
[0045]
When the sliding door shown in FIG. 2 is half open (with the sliding door opened rearward to about half of the full stroke), the harness fixing portion 17 on the vehicle body side does not move, and the protector 4 is integrated with the sliding door by about a half stroke. With this, the sliding member 7 rises along the second inclined portion 5a of the sliding contact guide 5 and is positioned substantially at the top 5c of the sliding contact guide 5.
[0046]
Thereby, the wire harness 6 draws a big ring in the front half part of the protector 4, and the wire harness 6 does not loosen from the lower mouth part 16 to the harness fixing part 17, and the protector 4 starts from the lower mouth part 16. The wire harness 6 is accommodated in a loop shape. Thereby, the surplus length (slack) of the wire harness 6 between the sliding door and the vehicle body when the sliding door is half open is reliably absorbed.
[0047]
When the slide door of FIG. 3 is fully opened, the protector 4 is retracted integrally with the slide door, and the sliding member 7 is lowered along the first inclined portion 5b of the sliding guide 5 and is positioned at the front end of the inclined portion 5b. Accordingly, the wire harness 6 is pulled out forward toward the harness fixing portion 17 of the vehicle body while being reduced in diameter within the front half of the protector 4. As the slide door is opened and closed, the wire harness 6 swings back and forth along the lower opening 16.
[0048]
As described above, as the sliding door is opened and closed, the sliding member 7 (7 ′) slides along the substantially mountain-shaped sliding contact guide 5 (5 ′), so that the wire harness 6 loops in the protector 4. The extra length is absorbed while the diameter of the wire harness is expanded, and the contraction operation of the wire harness 6 is smoothly and reliably performed while the diameter of the loop is reduced and pulled out to the vehicle body side.
[0049]
In FIG. 1, the wire harness portion 21 from the sliding member 7 to the harness fixing portion 17 is exposed to the outside of the protector 4, so that a flexible protective tube (exterior member) (corresponding to reference numeral 21) such as a corrugated tube is covered. It is preferable to make it waterproof and dustproof.
[0050]
Further, it is preferable to increase the rigidity of the wire harness portion from the sliding member 7 to the upper mouth portion 13 so as to be bent in a loop shape (a flexible ring cannot be drawn smoothly, and the loop shape collapses). End up). In particular, it is preferable that the rigidity of the wire harness 6 is not lowered when the outside air temperature and humidity are high.
[0051]
For this reason, for example, as shown in FIG. 6, an insulating coating 26 covering the core wire 25 of each electric wire 24 constituting the wire harness 6 is formed of a material that is hardly affected by temperature, such as polyethylene or fluororesin, or As described above, it is preferable to form the protective tube 28 that wraps the plurality of electric wires 24 ′ (electric wire bundle) from a material that does not decrease in rigidity due to temperature and humidity, as in FIG. 6.
